“Weird Al” Yankovic is releasing a video from his new album “Mandatory Fun”every day this week, and his latest is “Word Crimes,” a hilarious parody of Robin Thicke’s “Blurred Lines” that may as well have been called “Usage Nerds, Unite.”

In the text-heavy video, Yankovic will call you out for poor grammar, using lyrics such as:

“It’s a good time 2 lern some grammer? / Now did I stammer? / Work on that grammar. / You should know when / it’s less or it’s fewer / like people who were / never raised in a sewer.”

And this: “I hate these word crimes / like I could care less / that means you do care / at least a little.”
